W artykule przedstawiono analizę lotnych produktów rozkładu nowych odlewniczych spoiw polimerowych BioCo przy zastosowaniu metody termograwimetrycznej (TG) sprzężonej on-line ze spektrometrią masową (MS). W zakresie temperatury 40-600°C stwierdzono sygnały dla małych mas cząsteczkowych, co świadczy o zachodzeniu procesu degradacji, fragmentaryzacji łańcuchów polimerowych i tworzeniu się małocząsteczkowych...
Samples of sodium salt of the maleic acid-acrylic acid copolymer used as a binding agent in molding sands were investigated. Methods of thermal analysis (DTG, TG, DSC) were applied to assess the thermal stability of the investigated polymer sample by estimation of temperature and thermal effects of transformations occurring during its heating. Examinations were performed at the temperature range -100-1000...
